Constructor Detail

PrimeMeridian

public PrimeMeridian(java.lang.String name,
                     Unit unit,
                     double longitude)

Creates a prime meridian, relative to Greenwich.

Parameters:

name - Name to give new object.

unit - Angular units of longitude.

longitude - Longitude of prime meridian in supplied angular units East of Greenwich.

PrimeMeridian

PrimeMeridian(java.util.Map properties,
              Unit unit,
              double longitude)

Creates a prime meridian, relative to Greenwich.

Parameters:

properties - The set of properties (see Info).

unit - Angular units of longitude.

longitude - Longitude of prime meridian in supplied angular units East of Greenwich.

Method Detail

getLongitude

public double getLongitude()

Returns the longitude value relative to the Greenwich Meridian. The longitude is expressed in this objects angular units.

See Also:

CS_PrimeMeridian.getLongitude()

getLongitude

public double getLongitude(Unit targetUnit)

Returns the longitude value relative to the Greenwich Meridian, expressed in the specified units. This convenience method make easier to obtains longitude in degrees (getLongitude(Unit.DEGREE)), no matter the underlying angular units of this prime meridian.

Parameters:

targetUnit - The unit in which to express longitude.

getAngularUnit

public Unit getAngularUnit()

Returns the angular units.

See Also:

CS_PrimeMeridian.getAngularUnit()

hashCode

public int hashCode()

Returns a hash value for this prime meridian.

Overrides:

hashCode in class Info

equals

public boolean equals(java.lang.Object object)

Compares the specified object with this prime meridian for equality.

Overrides:

equals in class Info

addString

java.lang.String addString(java.lang.StringBuffer buffer)

Fill the part inside "[...]". Used for formatting Well Know Text (WKT).

Overrides:

addString in class Info

Parameters:

buffer - The buffer to add string to.

Returns:

The WKT code name (e.g. "GEOGCS").

toOpenGIS

final java.lang.Object toOpenGIS(java.lang.Object adapters)

Returns an OpenGIS interface for this prime meridian. The returned object is suitable for RMI use. Note: The returned type is a generic Object in order to avoid too early class loading of OpenGIS interface.

Overrides:
